OBJECTIVE: The long non-coding RNA (lncRNA) prostate cancer-associated transcript 1(PCAT-1) has been shown to be dysregulated and exert vital roles in tumorigenesis and progression of various malignancies. However, the precise molecular mechanism in the metastasis and invasion of HCC remain unclear. METHODS: The expression levels of PCAT1 derived from human HCC tissues and cell lines were analyzed through quantitative real-time PCR. QRT-PCR was also applied to detect the expression of HMGB1 and miR-129-5p...

Kittipat Charoenkwan, Zipporah Iheozor-Ejiofor, Kittipan Rerkasem, Elizabeth Matovinovic
BACKGROUND: Scalpels or electrosurgery can be used to make abdominal incisions. The potential benefits of electrosurgery may include reduced blood loss, dry and rapid separation of tissue, and reduced risk of cutting injury to surgeons. Postsurgery risks possibly associated with electrosurgery may include poor wound healing and complications such as surgical site infection. OBJECTIVES: To assess the effects of electrosurgery compared with scalpel for major abdominal incisions...

Chad A Purnell, Elbert E Vaca, Marco F Ellis
BACKGROUND: Orbital exenteration is a significant reconstructive challenge for plastic surgeons. Options described for these defects range from healing by secondary intention to free tissue transfer. The authors present our preferred reconstruction of orbital defects with free forearm-based flaps, which provides quality soft tissue and orbital contouring in 1 stage to consistently allow placement of bone-anchored implants for eventual orbital prosthesis. METHODS: This conical shape of the orbit is deconstructed into a "Pac-Man" type shaped flap that leaves adequate depth for a prosthesis...

BACKGROUND: Although everolimus potentially improves long-term heart transplantation (HTx) outcomes, its early postoperative safety profile had raised concerns and needs optimization. METHODS: This 6-month, open-label, multicenter randomized trial was designed to compare the cumulative incidence of a primary composite safety endpoint comprising wound healing delays, pericardial effusion (PCEs), pleural effusion (PLEs) needing drainage, and renal insufficiency events (estimated glomerular filtration rate [eGFR] ≤30/mL/min/1...

BACKGROUND: Using distraction osteogenesis (DO) to regenerate robust endogenous bone could greatly enhance postoncologic reconstruction of head and neck cancer. However, radiation (XRT) corrosive effects still preclude DO's immense potential. We posit that adjunctive pretreatment with the radioprotectant amifostine (AMF) can optimize wound healing and allow for successful DO with quantifiable enhancements in bony union and strength despite previous surgical bed irradiation. METHODS: Two groups of murine left hemimandibles were exposed to a human equivalent radiation dosage fractionated over 5 daily doses of 7 Gy...

BACKGROUND: Classic techniques of delayed prosthetic breast reconstruction use the mastectomy scar as an access route. As a result, the filling of the expander must be postponed until the wounds have healed. This creates an asymmetry between the breasts with the volume changes caused by the filling of the expander, which may occur over several weeks and cause considerable discomfort. METHODS: Delayed breast reconstruction was performed via the axillary incision made for sentinel lymph node biopsy or lymphadenectomy with endoscopic assistance and detachment of the pectoralis major muscle...

Chronic non-healing wounds represent a growing problem due to their high morbidity and cost. Despite recent advances in wound healing, several systemic and local factors can disrupt the weighed physiologic healing process. This paper critically reviews and discusses the role of nanotechnology in promoting the wound healing process. Nanotechnology-based materials have physicochemical, optical and biological properties unique from their bulk equivalent. These nanoparticles can be incorporated into scaffolds to create nanocomposite smart materials, which promote wound healing through their antimicrobial, as well as selective anti- and pro-inflammatory, and pro-angiogenic properties...

This overview addresses phenomena in cell- and molecular biology which are puzzling by their fast and highly coordinated way of organization. Generally, it appears that informative processes probably involved are more on the biophysical than on the classical biochemical side. The coordination problem is explained within the first part of the review by the topic of endogenous electrical phenomena. These are found e.g. in fast tissue organization and reorganization processes like development, wound healing and regeneration...

While platelets have long been known to be essential for maintaining hemostasis in the vasculature, their role in tissue repair, inflammation and innate and adaptive immunity is a more recent science. The ability of platelets to attach to the vessel wall, form aggregates and promote fibrin formation, key elements of blood clotting, has been said to both favor and dampen inflammation, to fight infection and to assure an adequate immune response. To fulfill their different roles platelets often synchronize with leukocytes and cells of the immune system...

Foot ulcers affect 15% of patients with diabetes, resulting in a great health burden. The occurrence and development of diabetic foot ulcers is associated with neuropathy, peripheral arterial disease, and infection. Several growth factors are involved in these processes, including epidermal growth factor, vascular endothelial growth factor, transforming growth factor-beta, fibroblast growth factor, and erythropoietin, which could promote wound healing of patients with diabetes. Thus, this review discusses the role of these growth factors in the pathogenesis of diabetic foot ulcers, aiming to achieve novel insights into the management of diabetic foot ulcers...

Wound healing on skin involves cell migration and proliferation in response to endogenous electric current. External electrical stimulation by electrical equipment is used to promote these biological processes for the treatment of chronic wounds and ulcers. Miniaturization of the electrical stimulation device for wound healing on skin will make this technology more widely available. Using flexible enzymatic electrodes and stretchable hydrogel, a stretchable bioelectric plaster is fabricated with a built-in enzymatic biofuel cell (EBFC) that fits to skin and generates ionic current along the surface of the skin by enzymatic electrochemical reactions for more than 12 h...

Mesenchymal stem cells (MSCs) are heterogeneous likely consisting of subpopulations with various therapeutic potentials. Here we attempted to acquire a subset of MSCs with enhanced effect in wound healing. We found that human placental MSCs expressing platelet-derived growth factor (PDGF) receptor (PDGFR)-β exhibited greater proliferation rates and generated more colony-forming unit-fibroblast (CFU-F), compared to PDGFR-β(-) MSCs. Notably, PDGFR-β(+) MSCs expressed higher levels of pro-angiogenic factors such as Ang1, Ang2, VEGF, bFGF and PDGF...

Wound healing in the inner ear sensory epithelia is performed by the apical domains of supporting cells (SCs). Junctional F-actin belts of SCs are thin during development but become exceptionally thick during maturation. The functional significance of the thick belts is not fully understood. We have studied the role of F-actin belts during wound healing in the developing and adult cochlea of mice in vivo. We show that the thick belts serve as intracellular scaffolds that preserve the positions of surviving cells in the cochlear sensory epithelium...

Iatrogenic laryngotracheal injury is the most serious complication of endotracheal intubation since this method of establishing airway was first described by Eugene Bouchut in 1858. Even today, subglottic stenosis is the most dreaded complication of intubation. This animal study is focused on the host tissue response to intubation induced injury resulting in subglottic stenosis and methods to prevent this complication. To assess the role of topically applied Mitomycin-C and Triamcinolone Acetonide in wound healing process following post-extubation subglottic injury...

The early surgical management of omphalocele major in Africa predisposes neonates to surgical complications which are often worsened by the presence of associated anomalies. Conservative management using available escharotics results in early skin cover by secondary wound healing. This delays the need for fascial closure and avoids neonatal surgical risks thus improving survival. We present a case of omphalocele major that underwent spontaneous closure during conservative management with honey dressing without surgical intervention...

β-transducin repeat-containing E3 ubiquitin protein ligase (β-TrCP) serves as the substrate recognition subunit for the Skp1-Cullin1-F-box protein E3 ubiquitin ligase, which recognizes the double phosphorylated DSG (X)2+nS destruction motif in various substrates that are essential for numerous aspects of tumorigenesis and regulates several important signaling pathways. However, the biological significance of β-TrCP in glioma progression remains largely unknown. A previous study by the authors demonstrated that the levels of β-TrCP protein expression in brain glioma tissues were significantly lower compared with non-tumorous tissues and that higher grades of gliomas exhibited lower levels of β-TrCP expression in comparison with lower glioma grades...
